The temperature regime in Saku is highly seasonal, offering travelers a variety of weather conditions throughout the year. The coldest month is traditionally January, when the average temperature drops to -0.8°C, and night frosts can reach -4.4°C.

These conditions are favorable for long walks, as exhausting heat is rare here.

During the transition seasons of spring and autumn, the weather is moderate and comfortable. For example, in May and October, average temperatures fluctuate around 12–14°C.

The climate in Saku features distinct seasonality, which directly affects the nature of precipitation throughout the year. The winter months, especially January and February, are the coldest, with average temperatures staying around or below freezing. During this time, precipitation falls mainly as snow, but the total amount is small. Winter is considered the driest season: snowy or overcast days occur on average 8 to 10 times a month, leaving plenty of time for clear weather.

As the warmth arrives, the situation changes. Spring brings a gradual increase in humidity, but the true peak of precipitation occurs in summer. June, July, and August are the rainiest months of the year. According to statistics, at the height of summer, rain can fall very frequently, reaching 20–22 days of precipitation per month. This is due to seasonal atmospheric fronts characteristic of much of Japan. Travelers planning a summer trip should be prepared for frequent rain and high humidity.

In autumn, the intensity of the rain gradually decreases. While the summer trend of frequent precipitation persists in September, by October the number of rainy days drops to 14, and November becomes one of the driest months along with the winter period. Thus, for those who prefer to avoid the rain, late autumn and winter are the most comfortable times to visit the city.

Traveling to Saku requires a thoughtful approach to packing, as the weather here is highly seasonal. Winters can be quite cold, with temperatures often dropping below freezing (down to -4°C), so be sure to bring a warm winter jacket or down coat, a hat, scarf, and gloves. Spring and autumn bring milder but more changeable weather. During these periods, the best approach is layering: combining T-shirts, light sweaters, and a windbreaker will allow you to feel comfortable both on cool mornings and warm afternoons.

Summer in the region is warm but not extremely hot (average high around +26°C); however, you should account for the high probability of precipitation. June and July are the rainiest months, when the number of wet days exceeds 20. Therefore, an umbrella, a light raincoat, and waterproof shoes will be your main companions. For summer walks, choose clothing made of natural, breathable fabrics to cope with the humidity more easily.

Regardless of the season, it's worth bringing comfortable walking shoes for a trip to Japan, as you'll be doing a lot of walking. Also, don't forget sunscreen and sunglasses, which will be useful in both spring and summer. If you are planning a trip in the shoulder season (March or November), be prepared for sharp temperature fluctuations and keep a warm sweater handy.
